The aging of fine wine is not necessarily restricted to reds only either. Fine Burgundy white wines are known to age for decades. I remember a producer in Austria who has in his cellar a Sylvaner 1947 that is still alive. Fine Mosel Rieslings are known to age for decades and we are not even talking about sweet wines that can have even longer longevity- I tasted 1909 Sauternes a few years ago and it was still singing! I know of some Tuscan producers who make white wines lasting for a couple of decades. Recently, I was in Ancona where we had a vertical tasting of Verdicchio dei Castelli di Jesi, the signature white grape of Marche. The 2000 vintage was very much alive and getting better (of course, like human romantic relationships, one cannot be sure how long it will keep up).
